Subject: [PATCH] contrib: remove mkimage-xxx scripts

These scripts have not been actively maintained for several Years, are
un-tested, and there may be better alternatives / implementations to
use for this purpose. A search on GitHub only showed a single active
use of one of these scripts; let's remove them, as there are no plans
to maintain (and test) these scripts.
